Box- like body 2,3 comprises the material 4 of powder pattern, is preferably coffee powder, and coffee powder is suitable for allowing extracting for example beverage of espresso and so on by pressurized hot water.The material 4 of powder type can be included between two filter element 5a and the 5b, and these two filter elements are suitable for the solia particle of for example granular coffee grounds and so on is remained in the bellows 1.
At least one this filter element arranged according to the present invention is preferably bottom filter element 5b, and this filter element is preferably made by the molded plastics such as polypropylene.Filter also can be made by metal or any other material that makes filter become substantially rigid.For term " rigidity ", it is meant that flat substantially body is can be in not being used to extract the bellows of beverage significantly not crooked under the pressure usually, for example under the pressure up to 10 crust.
The box-like body of bellows has base portion 6, and this base portion 6 is provided with and is used to flow out the delivery outlet 7 that has extracted beverage.Base portion preferably comprises a plurality of ridges 61, and these ridges 61 are suitable for forming slit 62 between base portion and lower filter 5b, extracts beverage to carry to delivery outlet 7.Groove is very little, and it is wide or littler to be preferably about 1mm.
Ridge 61 can be an arc, and is arranged to one heart around delivery outlet 7, thus groove 62 guide into each other and radially with one heart and interconnect, as in WO2005/092160 and WO2005/092162.
Filter 5b can be placed on the base portion 6 simply maybe can be attached in its peripheral edge margin.Preferably, ridge 61 supporting filter device 5b, thus prevent that filter is in the beverage extraction phase bending.
Delivery outlet 7 is preferably disposed on the central area of base portion 6 and is centered on by edge 8, and this delivery outlet 7 is formed barrier film 9 base closeds by the elasticity butter layer, and this barrier film 9 can be opened under pressure.
Barrier film 9 comprises the elastic membrane of being made by the material of elasticity or rubber like, and this material is preferably such as SEBS (block copolymer of styrene-ethylene-butylene-styrene) or Laprene (based on SEBS and polyolefin).
Elastic membrane can comprise through hole 10, and this through hole 10 is suitable for when bellows 1 is not used keeping barrier film 9 and the therefore sealing of beverage delivery outlet 7, and surpass certain value in the bellows internal pressure, for example 6 Palestine and Israels cause the distortion of through hole 10 and so beverage can be flow through when broadening.
As the substitute mode of through hole 10, elastic diaphragm can comprise blind hole (not illustrating in the drawings), and when the pressure in the bellows arrived certain threshold value, this blind hole can be opened because of breaking.
Elastic diaphragm 9 can be together co-molded with the box- like body 2,3 of bellows 1, and box-like body is preferably made by polypropylene, thereby removed the intermediate mechanical operation that barrier film 9 is fixed to the edge 8 of delivery outlet 7 from.
Perhaps, elastic diaphragm can be together co-molded with the support ring (not illustrating in the drawings) of rigidity, and this support ring is adapted to be interlocked in the outstanding cylindrical shape edge of delivery outlet 7.
Bellows 1 also comprises safety head 11, and this safety head 11 is installed in base portion 6 places of box-like body, thereby increases the axial dimension of box-like body.More particularly, lid 11 is fixed to the box-like body of bellows, thereby gives prominence to from base portion 6 along water (flow) direction, basic axis of symmetry direction at bellows.
Lid 11 preferably for example is mechanically fixed to the peripheral edge 15 of base portion 6 by interlock, thereby makes it can be fitted into the box-like body of bellows 1 rapidly.
Safety head 11 is provided with cylindrical shape shoulder 12, and this shoulder 12 is engaged on the barrier film 9, and is suitable for barrier film 9 is held against the delivery outlet 7 that is located in the base portion 6, thereby prevents that barrier film from spraying from bellows suddenly owing to the high pressure that reaches in extracting the beverage process.
Shoulder 12 can have at least one passage 14, thereby makes beverage discharge bellows 1 by safety head 11.For this reason, lid 11 comprises at least one outlet opening 13.
Lid 11 can be provided with the cylindrical wall 16 of second sealing, and this wall 16 centers on shoulder 12 and can be interlocked in the round base 17, and this round base 17 is formed on the base portion 6 around delivery outlet 7.Therefore wall 12 and 16 forms cylinder ring, and the beverage of discharging from the hole 10 of barrier film 9 can flow into this cylinder ring before arrival is located at outlet opening 13 in the safety head 11.
Referring now to bottom filter element 5b according to the present invention, this bottom filter element 5b preferably is used in the above-mentioned bellows 1.Obviously, those of ordinary skill in the art will appreciate that, this filter can be used in any bellows that comprises powdered rubber, can extract beverage from this bellows by using pressure (hydraulic) water.
Filter 5b is suitable for keeping equally effectively with filter paper the immobilized particles of the beverage of extraction from powdered rubber 4.Especially, filter 5b comprises the flat body 51 that is centered on by a thick rim 52, and this edge 52 is from the outstanding same degree in the two sides of flat body 51.A plurality of through holes 53 also are arranged in the flat body 51, the size of these through holes can stop solid particle by and can allow the water or the beverage that brew pass through.
Hole 53 can be according to any figure setting on whole flat body 51.For example, hole 53 can be as shown in Figure 3 according to latticed figure setting, perhaps as shown in Figure 4 along the concentric circumferences setting.Advantageously, if filter must be placed on a plurality of ridges, these ridges form the groove that is used for carrying to the bellows outlet beverage, then preferably, hole 53 is stacked on these grooves rather than on the ridge, thereby prevents that the hole from being blocked by ridge, therefore improves the homogenieity that beverage passes through and improves filter efficiency.
For example, the hole 53 of the filter 5b of Fig. 4 is provided with mutually with one heart, thus with concentric the aiming at of bellows 1 with radial slot 62.
Hole 53 has the shape with respect to the mid-plane F symmetry of flat body 51, thereby filter can insert in the bellows, and need not to consider the orientation of these holes with respect to powdered rubber in the bellows.
Especially, the diameter of each hole 53 at zone line 54 places will be narrower than the diameter of hole 53 at surf zone 55 places of flat body 51, thereby the section in each hole 53 is dispersed from middle regional 54 to surf zone 55 symmetrically.Two truncated cone shapes in hole 53 are compared and are cylindrically given filter better robustness, and also are useful in the molding process of filter 5b, especially in the time must opening mould and deviate from filter.
Be preferably from 1 ° to 20 ° or 30 ° more preferably about 10 ° from middle zone 54 the angles of divergence to arbitrary surf zone 55.The diameter at each zone line 54 place is preferably 0.1mm-1.0mm, more preferably is 0.2mm-0.4mm, is 0.25mm-0.35mm goodly.
In order further to improve filter efficiency, above hole can be arranged to as shown in Figure 6 along the staggered configuration 53a-53b of figure 58 (for example concentric circles figure), and this figure 58 is arranged on the delivery chute top such as groove 62 on the bellows bottom.Like this, the hole is the twice of the filter of Fig. 4 for example along this figure and the density above delivery chute basically.
The flat body 51 of filter 5b can be provided with the basic circular middle section 56 that does not have the hole.The middle section 56 of this " complete " is particularly suited for comprising the bellows of the elastic diaphragm that is used to produce butter layer, such as the bellows of Fig. 1 and 2, directly impacts barrier film 9 because it has avoided high pressure to brew water.
And, there is not the hole can improve the filtration of filter 5b at middle section 56.In fact, because below the middle section of filter, have the open area, be delivery outlet 7, so filter 5b can be in the beverage extraction phase bending.If have the hole at middle section 56, then these holes can become greatly, so the deterioration filtration.
For this reason, the diameter of the complete middle section 56 of filter 5b is chosen to be the diameter that is substantially equal to delivery outlet 7.One skilled in the art will recognize, that the filter 5b that has the zone that does not have any through hole can be used for containing in filter meeting knee the bellows of any extraction beverage of very large open area.
Filter 5b can comprise that also this undercutting 57 is useful around the undercutting 57 of the inner peripheral at edge 52 in molding process.
In fact, preferably use two symmetrical mold to make according to filter of the present invention, these two moulds have accordingly towards each other truncated cone shape pin to form hole 53, and in the time must deviating from filter, filter remains on undercutting 57 places.
It has been found that the present invention has realized re-set target fully, because can significantly simplify the assembly operation of the bellows that is used to form beverage.Although the present invention is thought of as the bellows that is particularly useful for being suitable for preparing espresso, but it also can more be widely used for comprising the bellows of Edible material in all cases, and this bellows is suitable for forming beverage or being suitable for being used in filter stand in beverage or the espresso extractor by diafiltration substantially.
Therefore the bellows and the filter of imagination can have multiple modification and modification, and all these within the scope of the appended claims.Also available other the technical equivalent elements of all details is replaced.
In fact, used material and size can be as requested with the prior art development level and for arbitrarily.
